How Much Does It Cost to Make Cold Brew at Home?
A cold brew from the counter runs $4.50–$5.50. Made at home it's just coarse coffee steeped in cold water — pennies to about $0.30 a glass. Here's where that number comes from, and why the gear pays for itself in a handful of glasses.
The short answer
Cold brew is the cheapest coffee drink to make at home because it needs no machine to start — just grounds, water, and time. A big pitcher costs roughly $2–$4 in beans and yields about 6–8 glasses, so each 16 oz glass lands somewhere between a few pennies and ~$0.30 — versus $4.50-plus out.
What actually goes into the cost
Beans (the main cost)
Cold brew uses more grounds per batch than drip — a strong 1:5 to 1:8 coffee-to-water ratio — because you're making a concentrate to dilute later. Even so, a single bag still makes many glasses. Coarse-ground coffee is all it takes; no fancy roast required.
Water & time
The other half of the recipe is free. Coarse coffee steeps in cold water for 12–18 hours, then you strain it — no heat, no pressure, no machine. Time does the work while the jar sits in the fridge.
Nitro (optional)
Want the café-style creamy, cascading pour? A nitro maker charges the brew with N₂ (nitrogen) cartridges — a small recurring consumable on top of the coffee, and the only ongoing add-on cold brew has.
The one-time cost: the gear
None of it is required, but a little kit makes life easier. A mason jar and filter runs about $15, a dedicated cold brew maker about $35, and a nitro cold brew maker about $95. Because the per-glass savings are around $4-plus, even the nitro rig breaks even after a couple dozen glasses — and the jar-and-filter setup pays for itself in a handful.

Run your own numbers
Your savings depend on how many glasses you drink, your beans, and whether you go nitro. The calculator does the whole tally — weekly, monthly, annual, and the exact break-even point for the gear you pick.

Is it worth it?
For cold brew, almost always — the barrier is nearly zero. You can start with a jar you already own and be sipping the next morning for pennies. If you drink it regularly, a maker or nitro rig pays itself off fast and every glass after is money you keep. Run the numbers to see your break-even before you buy anything.
Food-safety note: cold brew is never heated, so use clean equipment, keep the concentrate refrigerated, and drink it within about a week. Caffeine per glass varies widely with your brew ratio. Full terms & disclaimers →
